Breast Cancer-Related Lymphedema Risk-Management Behaviors Among Chinese Breast Cancer Survivors and Relationships with Socio-Demographic and Clinical Characteristics: A Longitudinal Study

Abstract

Purpose We sought to determine changes in breast cancer-related lymphedema (BCRL) risk-management behaviors in the six-month period after surgery among Chinese breast cancer survivors and to explore the relationship between their socio-demographic and clinical characteristics and these behaviors. Patients and Methods A longitudinal study design was adopted. Females aged ≥18 years with a first breast cancer diagnosis and who had undergone modified radical mastectomy were recruited from a cancer hospital in China. Respondents with a history of other malignant tumors, mental illness, or cognitive impairment were excluded from the study. Socio-demographic and clinical factors were assessed at baseline. BCRL risk-management behaviors were assessed with the Lymphedema Risk-Management Behavior Questionnaire (LRMBQ) and Functional Exercise Adherence Scale (FEAS) in the first, third, and sixth months after surgery. Repeated-measures analysis of variance was used to examine changes in BCRL risk-management behaviors over the three study time periods, and a generalized linear mixed model was used to determine socio-demographic and clinical factors associated with BCRL risk-management behaviors. Results A total of 166 participants completed all three assessments. The scores of the total LRMBQ and its “Skin care” and “Lifestyle” subscales did not change significantly, but those of the “Avoidance of limb compression and injury” and “Other matters requiring attention” subscales changed over the three study time periods. Additionally, scores of the total FEAS and most of its subscales changed over the three study time periods. Furthermore, BCRL risk-management behaviors were significantly related to patients’ geographic residence, education level, and tumor stage. Conclusion Some dimensions of BCRL risk-management behaviors changed over time, and several socio-demographic and clinical factors are related to BCRL risk-management behaviors. It is recommended that health care professionals consider the dynamic nature of BCRL risk-management behaviors and related factors when planning health education and promotion interventions.
